Ambry Genetics

Oct 20, 2024

The c.695A>G (p.N232S) alteration is located in exon 4 (coding exon 3) of the THUMPD3 gene. This alteration results from a A to G substitution at nucleotide position 695, causing the asparagine (N) at amino acid position 232 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
